The yield of chemicals found in the e-cigarette vapor varies depending on, several factors, including the e-liquid contents, puffing rate, and the battery voltage. [14] A 2017 review found that "Adjusting battery wattage or the inhaled airflow modifies the amount of vapor and chemical density in each puff."
A later-generation box mod e-cigarette. An e-cigarette is a handheld battery-powered vaporizer that simulates smoking, but without tobacco combustion. [1] Once the user inhales, the airflow activates the flow sensor, and then the heating element atomizes the liquid solution. [5]
An electronic cigarette (e-cigarette), or vape, [note 1] [1] is a device that simulates smoking. It consists of an atomizer, a power source such as a battery, and a container such as a cartridge or tank. Instead of smoke, the user inhales vapor. [2] As such, using an e-cigarette is often called "vaping". [3]

[10] [9] PICA was to be given a new sublease from the PTT, excluding the bar area, which was to be opened up to an expression of interest ...
A 2017 study reported that battery output voltage positively influenced carbonyl vapor levels. [229] A 2015 study reported that e-cigarettes using higher voltages (5.0 V) [ 216 ] can emit carcinogens including formaldehyde at levels comparable to cigarette smoke, [ 138 ] creating a lifetime cancer risk 5 to 15 times greater than long-term smoking.
